"Second, go to the scene of the crime and visit, there are not many cars crossing the bridge that night, go and see if any driver sees all this, it is best to have a dashcam to take pictures."

"Yes,"

"Third, and the strangest thing for me, according to the camera, I can see that Liu Changfeng walked to the temple by himself, not forced by others or taken by others. But when you encounter this situation, isn't your first reaction to go to the hospital to save your life? And the hospital where he worked was only ten minutes away from where he was at the time, so why did he go so far and spend half an hour crawling to the door of the ruined temple? None of this makes sense, unless ........."

Jiang He asked her, "Team Li, unless what?" ”

"Unless, he's bent on death."

Jiang He asked: "But why should a person who is bent on death throw away the murder weapon?" Why destroy the camera? Why don't you find a quiet place to die? On the contrary, I went to work normally during the day, is it all improvised? And he made a temporary decision, bent on death, and actually carried a knife with him? Wouldn't it be faster to jump straight off the bridge? Last but not least, why did he climb to the door of the ruined temple? Lying in front of that stone statue? ”

After Li Ruoqing heard it, he replied to him: "I didn't expect you to become smarter recently, what you said are all problems, all questions, and we need to solve them little by little." In addition to what I just said, there are two more people who need you to help me find it, the first one is the child in Wang Dashan's memory, it should be a boy, you turn to the previous case, help me investigate the family of the victim of the case, if the little boy witnessed everything, and the police did not find the murderer, let him find it, it is very likely that he will take revenge. Second, help me find out what the scar on Dr. Liu Changfeng's face is? ”

Jiang He said: "The last time the two of us inquired separately, I asked this question, and several nurses said similar answers, which should be correct. They said that when Dr. Liu Changfeng was teaching some freshmen and foreign doctors to do experiments, he accidentally injured himself by losing his mind. ”

"Was that experiment difficult?"

Jiang He replied: "No, it looks very dangerous, but it is very common for doctors like them, and interns who are a little more familiar with it may not have any accidents." Not to mention the deceased, a director-level doctor, so something must have happened at that time. ”

Li Ruoqing nodded: "Please go to that hospital again, find a way to get photos of all the interns and foreign doctors who participated in the experiment at that time, they usually take some group photos as souvenirs, you only need to find one of them and bring back a few copies." ”

"Okay."

Li Ruoqing nodded: "I'm sorry for you, maybe I've figured out half of the matter now, let's not think about Liu Changfeng's suicide first, that little boy is very likely to be discovered by Liu Changfeng as an intern in a hospital, Liu Changfeng and the little boy turned around, trying to escape the boy's revenge and legal sanctions, but unfortunately he was killed by the little boy, right on this bridge." At the moment when he might be killed, Liu Changfeng figured it out, so he didn't choose to go to the hospital or call the police, but came to the temple, finished the last confession twenty years ago, and silently greeted death. The reason why he threw away the murder weapon was to protect the boy, because Liu Changfeng was a kind-hearted doctor, and he didn't want to be punished by the law and sentenced to death because the murder weapon boy was caught by the police. In that case, wouldn't he owe the boy another life? ”

Jiang He nodded: "That is to say, if we can find this boy, basically the case can be solved." ”

Li Ruoqing said: "There is also evidence, first, the evidence that the boy participated in the hospital experiment, in fact, it doesn't matter whether this is or not, at most it can prove that the scar on Dr. Liu's face is related to the boy." The second point is more important, we must need human or physical evidence to prove, the boy and Dr. Liu were on this bridge that night, and everything I reasoned about, otherwise we can only reason, without any evidence. Even if someone is caught, the final result will be nothing more than 48 hours of detention. ”

Jiang He nodded, and everything was done at once, and the leaders above also attached great importance to this case, and quickly approved the request to salvage the murder weapon.

On this day, according to the blood stains dripping on the bridge, Li Ruoqing roughly simulated the lost range of the murder weapon under the bridge, and then asked professional divers to go down to salvage it.

A total of five divers, more than a dozen criminal policemen, and several professionals, as well as Li Ruoqing and Jiang He, were waiting silently beside them.

Soon two came out, and there was no good news, but they changed the oxygen cylinder and rested for more than ten minutes, and then dived into the water again.

Above, sonar boats are constantly detecting the presence of metal or other foreign objects underneath.

It's a pity that it's too difficult to do this, the Xuanwu River has been around for many years, and there are a lot of metal objects in it, and the sonar detection is blurry, and it is impossible to accurately determine which one is the murder weapon?

Almost two hours later, one of them popped up and made an OK gesture.

Everyone was in a good mood, indicating that the murder weapon had been found.

The diver brought the dagger out, and most of the blood on it had been soaked in seawater, but the red blood stains were still faintly visible.

Even if it's all gone, it's nothing, anyway, all of them can be tested when the time comes.

The dagger looked like a fruit knife, Li Ruoqing was a little happy, everything was according to his own reasoning, as long as it could be proved that this was the real murder weapon, and it was the little boy's thing.

Then the murderer has basically been locked, and this case can be over.

Seon lost his horse, but he didn't know if it was a blessing.

This truth is always the most correct, just when Li Ruoqing was still glad that he had found the murder weapon.

There's bad news over there.

Jiang He stood for a week, but did not find any drivers or vehicles that witnessed Liu Changfeng and the boy.

Although this bridge is relatively well repaired, there are really not many cars coming and going, and it is not a provincial road.

Even if someone passes by the car, it may be passing by Xuanwu City, and it is really not easy to find it within the whole Longxia area, it is more difficult than looking for a needle in a haystack.

However, Li Ruoqing can still understand this, and she is also mentally prepared.

After all, this task is almost impossible.

At this time, another news came from the criminal police headquarters, which had verified the car accident case 20 years ago that Wang Dashan had said, and confirmed that the situation was true.

And the family of the victim of the case has been found, and they live in Xuanwu City.
